ISO 16067-1 testing?

Do you folks know of manufactures, or anyone else, publishing results of
scanner testing using ISO standard 16067-1 "Photography -- Electronic
scanners for photographic images - Spatial resolution measurements -- Part
1: Scanners for reflective media"? Do you know of anyone who has done any
testing using this standard?

Thanks,

I have not seen any scanner producer publishing their results based on
that standard (truth hurts?), but there are a few people in this
newsgroup that do their own tests on the scanners (and camera lenses
and film/sensors) that are available to them.

A Google search for "slanted edge" should return some of the
contributions/threads
(http://groups.google.com/groups?as_q=slanted+edge&as_ugroup=comp.periphs.scanners).
A search for ISO-16067 should also produce some results. The
rec.photo.digital or rec.photo.equipment.medium-format or
rec.photo.digital.slr-systems groups will also produce some results
with those search terms, although not necessarily about scanners.

You can quantify your own equipment's results with a program like
Imatest (www.imatest.com), although it is possible to do the tedious
calculations "by hand" (using a computer/calculator).

A site like http://www.imaging-resource.com/ has started to report
test results by using Imatest, but scanners seem to have been dropped
from their list of priorities.
